This invention provides a foam barrier which prevents substantial migration of plasticizer from a plasticized polymeric article, such as a PVC cable jacket, into a gel sealing material in contact with the article and prevents substantial migration of oil from the gel material into the article while not significantly interfering with the sealing contact between the gel material and the surface of the article.

Crosslinkable gel compositions cure rapidly to provide gel compositions which possess superior combinations of chemical and physical properties and aging resistance. These compositions are particularly useful for environmentally protecting substrates, especially electrical conductors, connectors, and splices and for sealing around jacketed cables, for example where they enter splice cases.

There is disclosed a cable closure which includes a central closure body and a pair of end caps preferably made from structural foam situated at each end of the closure body. There is also disclosed a cable block which includes void filling material selectively inserted among the insulated conductors of the cable and a directional control device which consists of a conduit also selectively inserted among the insulated conductors of the cable. Together the cable closure, cable block and directional control device make up the splice closure system. There may also be provided a heat recoverable seal adhesively attached to the cable closure in which case there will also be provided means for preventing milk-off of the seal from the cable closure. finally, there is disclosed a method for forming the cable block.

A composition comprises a blend of (a) a first crystalline fluoroplastic which is an ethylene-tetrafluoroethylene copolymer, in an amount between 30 and 70 weight %; (b) a second crystalline fluoroplastic which is a terpolymer of tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride, in an amount between 30 and 65 weight %; and (c) a fluorinated thermoplastic elastomer which is a block copolymer having at least one elastomeric segment comprising tetrafluoroethylene, vinylidene fluoride, and hexafluoropropylene repeat units in a mole ratio 45-90:5-50:0-35 and at least one nonelastomeric segment comprising tetrafluoroethylene and ethylene repeat units, in an amount between 5 and 25 weight %. The fluorinated thermoplastic elastomer acts as a compatibilizer for the two fluoroplastics. The composition exhibits improved flexibility, tensile strength, and/or elongation.

This invention provides a planar sealing article including: (a) a driver including a crosslinked foamable polymer, and (b) a sealer including an uncrosslinked foamable polymer in intimate contact with the driver and surrounding the driver in the plane of the article, the sealer having a plurality of apertures therethrough. The sealing article is especially adapted for forming a seal between a plurality of substrates and a bounded opening through which the plurality of substrates pass.

A gel and container means capable of protecting a binding post and drop wire from moisture and corrosion is provided which will effectively prevent the exposure of the drop wire and binding post cap and screw from moisture and corrosive atmospheres without the need for a pressure maintaining means other than the combination of the cap and gel. The pressure of the gel is maintained on the binding post through the extraction of plasticizers from the container means causing a shrinkage.
